BIT NAME DEFAULT DESCRIPTION
0 12ABS - High indicates BLKA commanded high.
1 12APS - Low indicates V
PASSA
> VOUT12A + 6 V.
2 3ABS - Low indicates IN3A > OUT3A.
3 12BBS - High indicates BLKB commanded high.
4 12BPS - Low indicates V
PASSB
> VOUTB + 6 V.
5 3BBS - Low indicates IN3B > OUT3B.
6 3AGS - Low indicates channel 3A gate is driven on (VGATE > VIN + 1.75 V).
7 3BGS - Low indicates channel 3B gate is driven on (VGATE > VIN + 1.75 V).
12ABS This bit goes high when the 12A ORing logic commands the BLKA pin high (25 V) and the BLKA FET
should be on.
12APS This bit goes low when the 12A PASS pin is above the timer start threshold (OUT12A + 7 V), indicating
that the 12A PASS FET should be on.
3ABS This bit goes low when the 3A ORing logic commands the pass 3A FET on, indicating that a reverse
blocking condition does not exist.
12BBS This bit goes high when the 12B ORing logic commands the BLKB pin high ( 25 V ) and the BLKB FET
should be on.
12BPS This bit goes low when the 12B PASS pin is above the timer start threshold (OUT12B + 7 V), indicating
that the 12B PASS FET should be on.
3BBS This bit goes low when the 3B ORing logic commands the 3B pass FET on, indicating that a reverse
blocking condition does not exist.
3AGS This bit goes low when the 3A FET gate-to-source voltage exceeds 1.75 V, indicating that the 3A FET
should be on.
3BGS This bit goes low when the 3B FET gate-to-source voltage exceeds 1.75 V, indicating that the 3B FET
should be on.
